Definitions

  • a corresponding pyrotechnic circuit breaker is designed in particular for an electrical system of a motor vehicle and is accordingly preferably used in a vehicle electrical system of a motor vehicle.
  • the pyrotechnic circuit breaker comprises a one-piece, one-piece current-carrying sheet or stamped sheet metal, for example of aluminum, with at least two connection elements or connection arms and with at least one fuse conductor connecting the at least two connection elements.
  • at least in the installed state of the pyrotechnic circuit breaker of one of the at least two connection elements typically forms an input terminal for a Stromzuhnetechnisch and the other of the at least two connection elements an output terminal for a Stromabloom protest.
